WEIGHBEAM.

Application filed July 24. 1924. Serial No. 728,028.

My present invention relates to typeregistering scale beams, and comprises the novel features of construction as hereinafter set forth.

In the accompanying drawings, wherein 1 have shown an illustrative embodiment of the invention Figure 1 is a plan view of a scale beam and registering poise of my improved con struction Fig. 2, is a front elevation thereof;

Fig. 3 is an enlarged view of the beam and poise, parts being broken away to show the underlying structure;

Fig. 4 is a transverse section taken ap-.

proximately on the line 44, of Fig. 3.

Fig. 5 is a transverse section taken approximately on the line 55-43 of Fig. 3, and

Fig. 6 is an enlarged transverse section of the beam.

The main scale beam 10, carrying pivots 11 that are supported in bearings 12 mounted in a stand 13, is provided with a registering poise 14, of the general type shown in the United States Letters Patent granted to Charles A. Blodgett, March 21, 1916, No. 1,176,128. The beam, beyond the pivots 11, is provided with a loop 15 to which the rod connecting the beam with the weighing mechanism is suspended, while at its opposite end, the tip of the beam is passed through a trig-stand 16.

The poise 14 carries an adjustably mounted auxiliary poise 17, in the form of a bar that is slidably mounted in a channel 18, the poise 17 riding on a plurality of spaced rollers 19, as shown by Fig. 3. The lower face of the poise 17 is preferably provided with a rack 20 meshing with a pinion 21, which may be revolved by a,

knob 22 to set the auxiliary poise in proper position.

Referring now particularly to Fig. 4 of the drawings, it will be noticed that the top of the beam 10 is made in the form of a track 23 comprising two spaced apart parallel portions on which rollers 24 of the poise 14 travel. Between the poise track is a ridge having notches 25 that are adapted to be engaged by a spring-pressed latch 26, mounted in the top of the poise.

The poise 14, below the track 23, is open on the front, while the back portion 27 thereof, is extended downwardly and forwardly, as at 28, around the lower portion of the beam 10. The beam is inclined outwardly, as at 29, and then vertically downward, as at 30, so that the lower portion thereof is offset considerably from the upper or track portion thereof.

Thus it will be noticed that the. configuration of the poise (in cross-section) is such that it simulates a reversed letter L, while the beam 10 (in cross-section) may be said to be of substantial Z form. Furthermore, it will be noticed that the auxiliary poise 17 is mounted in the portion 28 or the laterally offset part of the poise 14.

The inclined portion 29 of the beam is provided with scale graduations 31 of large denominations, such for instance, as thousands of pounds, and the notches 25 on the top of the beam correspond with the graduations, thereby enabling the poise 14 to be accurately set in position.

Carried by the poise 17 is an index 32, which co-operates with a graduated scale 33 on the main poise 14 for indicating the fractional weights interediate the larger denominations.

The type-registering mechanism comprises a series of type characters 34 on the lower edge of the main scale beam, said type corresponding to the scale graduations on the inclined portion of the beam, and a second series of type 35 on the bottom of the auxiliary poise 17. A platen 36 is mounted in the poise 14 for pressing a ticket against the type to take an impression therefrom, the ticket being inserted through a slot 37 in the front face of the poise, while the platen is actuated by means of a lever 38, pivotally mounted on the bottom of the poise. Associated with the lever 38 is a handle 39 fixed to the underside of the poise in front of the lever, so as to provide a pistol grip.

One of the principal advantages of the construction above described is that when the poise 14 is positioned on the portion of the beam nearest the pivots 11, and the auxiliary poise 17 is extended so that the index 32 is at, or near zero (see Figs. 1 and 2) the poise 17 can readily pass in front of the stand 13 and loop 15, whereas with constructions that have heretofore been used, in which the auxiliary poise was located beneath the beam, it was always necessary to modify the form of loops and stands used, so as to provide clearance spaces for the auxiliary poise in its movement-s.

W'h at I claim is 1. it weigh-beam of substantially Z-form in cross-section.

2. In a. scale, the combination with a weigh beam of substantially Z-form in cross-section, of a poise carried by said beam, said poise being substantially L.- shaped in cross-section.

3. A. weigh-bean'i con'iprising asolid bar having a portion inclined inwardly, and the lower side of said forward portion carrying printing type.

4:. A weigh-beam con'iprising a solid bar having a portion inclined forwardly, the lower side of said forward portion carryprinting type, and scale graduations formed on said inclined portion.

5. A weigh-beam having a poise track on its upper portion and carrying printing type on its lower portion, the portion of the beam between said track and type being inclined whereby said type is disposed forwardly of said track.

6. A weigh-beam having a poise track on its upper portion and carrying printing type on its lower portion, the portion of the beam between said track and type being inclined whereby said type is disposed forwardly of said track, and scale graduations formed on said inclined portion.

7. A beam for weighing scales having a poise track on its upper portion, and carrying printing type on its lower portion, the said type being off-set with respect to the said track.

8. In scale, in combination, a weighbeam having a poise track on its upper face and its lower portion off-set with respect to the said track, and a poise mounted on said track and surrounding the said off-set portion of the beam.

9. In a scale, in combination, a weighbeani having a poise track on its upper face, the lower portion of the said beam being oil-set with respect to the said track, printing type carried by the off-set portion of the beam, a, poise mounted on the weighbcam track and surrounding the said off-set portion or" the beam, an auxiliary poise carried by said first named poise, and printing type on said auxiliary poise oo-operating with the type on said weigh beam.

10. In a scale, the combination with a pivotally mounted beam, of a poise slidable onsaid bean]. and an auxiliary poise adjustably mounted in said first mentioned poise, said auxiliary poise being so positioned with respect to the beam that it will pass in front of said beam pivots when the poise is shifted on the beam.

In testimony whereof I hereunto sign my name.
